LIFESPAN

FOR A LONG LIFESPAN…

For a long lifespan…

AH-300-K-1-6 While the measuring electrode presents a closed glass surface towards its surroundings,the reference contains an opening – via the junction substances can get in and out. There- fore the lifespan of a sensor strongly depends on the protection of the reference electrode.

Ceramic junction…

Limited exchange. Low maintenance in combination with gel electrolyte. For low salt contents with refillable liquid electrolyte. For special applications and process control with protruding junction that can be abraded or covered with a protective membrane.

Platinum junction or glass sleeve…

For pure water we recommend liquid electrolyte and junctions with high KCl passage. This can be 3 ceramic junctions, a Platinum twine, or a glass sleeve with adjustable passage.

PTFE junction or open hole…

For effluents and particle-containing water we recommend the PTFE junction with a large, non-sticking surface, or even an open hole, in combination with a solid electrolyte.

Double chamber reference…

Two separate chambers with independent refill options. For a maximum of protection and versatility. For example with a chloride-free outer filling to protect damageable solutions. Dr. A. Kuntze| gutes Wasser mit System.
